On my Pass X150.5 and my friend's X250.5, here's our experience on powercords and also power conditioners:
The Shunyata power cords made a significant improvement on our Pass amps. Starting with the Copperhead, we went to the Taipan Helix Alpha, then Python Helix Alpha. Good improvement on each step and best with the Python.
But, plugging the amps into Shunyata Hydra power conditioners also made BIG improvements. We've used the Hyra 2, 6 and 8.
For those who say plug the amp into the wall, not a power conditioner, that doesn't hold, imo, with the Shunyata Hydras, which are not in any way power limiting, and the sound is much improved in many areas, detail, transparency etc.
There is absolutely no question on the above improvement.
